A common synthetic route to a-tocotrienol and a-tocopherol has been accomplished by a biomimetic cyclisation that yields the chromanol ring. The chirality at C2 of the chro- manol was induced by a covalently attached chiral dipeptide. Its terminal Asp participates in the enantioface-selective pro-tonation of the double bond of the a-tocotrienol precursor. a-Tocotrienol was diastereoselectively hydrogenated to a-tocopherol.
